Abstract
A system for delivery of radiation to a target portion of a native tissue is provided. The system includes a catheter having a main catheter body. The main catheter body includes an outer catheter surface and an inner catheter surface that defines a longitudinally oriented lumen. The lumen extends between longitudinally spaced proximal and distal catheter face surfaces extending laterally between the inner and outer catheter surfaces. A sheath covers at least a portion of the outer catheter surface. The sheath includes a tapered portion protruding substantially longitudinally distally from a portion of the distal catheter face surface. A plurality of tubes extends through the lumen towards the distal catheter face surface. Each tube of the plurality of tubes is configured to selectively guide exposure of a radiation source to the target portion of the native tissue.
